Error: BLS is exposed as Web Service

[Former Member]

Hi All,

I have one small BLS which will get two integers as input params and yield their Sum as output param with Integer Data type. This BLS itself is working fine. Now while generating WSDL file on this BLS, I have use the URL like following

http://<server>/XMII/WSDLGen/<trasnactionpathname>/<transactionname>; which is running fine in browser session itself

But when Iu2019m trying to test the same WSDL in WSNavigator from Netweaver, this is giving error as follow

The markup in the document following the root element must be well-formed

And while checking the log in NW this is saying as follows

An error occurred while loading WSDL: http://<Host>:<Port>/XMII/WSDLGen/Default/<Package>/<BLS>;

So is there anything Iu2019m missing or is there anything to be configured at NW server side? Please help

Our MII version : 12.1.5

Found under System Management...System Administration in the Menu.jsp, what is your current configuration setting for "WSDLGenSecurityEnabled"?

If this is checked, an authenticated browser session will work fine, but you will likely get the NW login screen (html) when calling the WSDLGen servlet URL. This would also produce the "The markup in the document following the root element must be well-formed" if you tried to load xml but received html.

Hi Jeremy,

Thank you so much for your help.

I have unchecked the "WSDLGenSecurityEnabled" check box and Now I am able to test the same Web service from WsNavigator.

Thanks again

Chandan

Try it using the Runner service. Look in the help section for the syntax or look here in the forum for some additional specific information.

Regards,

Hi Jeremy,

Thanks for your help. I am able to test it from WSnavigator but at the time of execution within XacuteRequest: two field are coming always.

XacuteRequest: 1) LoginName 2) LoginPassword:

Eithere I need to put the value there or I need to put the value within a popup when I click on next button.

But if I consume the Web Service from other place like as SAP ECC and trying to execute it then again I need to put the value for XacuteRequest: 1) LoginName 2) LoginPassword: as hardcode.

Is there any solution that I can avoid these two fields.

Thanks

Chandan

If a trusted login exists between the requesting system and the NetWeaver instance where MII is running, then you shouldn't need to use the exposed user/pwd fields.

Similar to the WSDLGen URL working when security is enabled and you are using IE with a valid session, your ECC webservice call to MII should work if UME trusts the incoming user session.
